     NOTES:
 
-    Since this configuration is based on the ELF configuration, all of
-    the notes for that configuration also apply.
+    NOTES:
 
-    1. This configuration is based on the elf configuration.  Primary
-       differences between the two configurations are noted below:
+    1. This configuration uses the the USART3 for the serial console
+       which is available at the "DBGU" RS-232 connector (J24).  That
+       is easily changed by reconfiguring to (1) enable a different
+       serial peripheral, and (2) selecting that serial peripheral as
+       the console device.
+
+    2. By default, this configuration is set up to build on Windows
+       under either a Cygwin or MSYS environment using a recent, Windows-
+       native, generic ARM EABI GCC toolchain (such as the CodeSourcery
+       toolchain).  Both the build environment and the toolchain
+       selection can easily be changed by reconfiguring:
+
+       CONFIG_HOST_WINDOWS=y                   : Windows operating system
+       CONFIG_WINDOWS_CYGWIN=y                 : POSIX environment under windows
+       CONFIG_ARMV7A_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows
+
+       If you are running on Linux, make *certain* that you have
+       CONFIG_HOST_LINUX=y *before* the first make or you will create a
+       corrupt configuration that may not be easy to recover from. See
+       the warning in the section "Information Common to All Configurations"
+       for further information.
+
